Reviewed commit: 9b14662
Overall direction: separating reusable upstream capabilities from moq.pro integration and making release dependencies explicit is sound. One acceptance-criteria correction and one nonblocking scope question:
-
Reconcile exact percentiles with lossy buckets: quest/m1/bench-buckets.md:22–24 permits log-linear buckets, but lines 7–9 and 30–31 require equality with concatenated samples. Lossy buckets cannot reproduce exact raw-sample percentiles; the existing 60,000 ms overflow bucket also loses that information. Specify that the comparison bins concatenated samples using the same layout and overflow policy, or define an error tolerance. This makes the proposed acceptance test achievable without accidentally claiming lossless percentiles.
-
Nonblocking scope question: quest/m1/lite07-finalize.md:22–23 calls the freeze checklist exhaustive, while cluster-routing/routes.md:5–7 still assigns its new ROUTE/ANNOUNCE wire to the unspecified wip version. Please name whether routing gates lite-07 or is deferred to lite-08, so the two implementation plans have an unambiguous ordering.
Verification limits: inspected the full current 16-file documentation diff and relevant repository context, including the rebased dependency paths. These observations remain from the earlier read-only inspection; no earlier review was published. No tests or runtime/hardware validation were run, and this is not a CI or implementation approval.

Addressed in 1e059ab:
CodeRabbit items applied: stats-linger keeps cumulative totals while live gauges read zero during the linger; preflight only observes the unannounce, which the publisher owns; gpu-health states which memory values are process-scoped and which device-wide; rtsp-import scopes fresh epochs to reconnects, while rendition URLs share one broadcast's epoch. The moq.pro links are private by design, so they stay as they are. (Written by Claude Opus 5.5) |

Reviewed commit: 1e059ab
Both observations from my previous review are addressed:
- bench-buckets.md:7–11,32–34 now defines equality at bucket resolution and applies the same overflow rule in the acceptance test.
- lite07-finalize.md:22–26,38–41 explicitly excludes unlisted wire work from the freeze set and recommends routing for lite-08 unless the maintainer adds it.
No new actionable findings in this revision. Overall direction remains sound: reusable upstream work has clear ownership, and the revised acceptance criteria and lifecycle boundaries are more precise.
Verification: reviewed the current documentation diff and all seven files changed since 9b14662; this is one follow-up commit, not a rebase. No tests, runtime or hardware validation were run; this comment is not implementation or CI approval.

The route layer lands in lite-07 and gates its finalize, which needs the whole subscribe-ranges line; wire quests target the wip version until the maintainer cuts it, so the auth line moves off lite-06. Stats linger moves to m0 with a new epoch after the linger, HLS bounded playlists leave the archive line, GPU health keys by the render node, and the RTSP library takes a caller broadcast whose owner restarts every session on a jump.

Reviewed commit: 87ab8af
No new actionable findings in the current documentation diff. The earlier histogram issue remains fixed; bench-buckets.md:5–12 now also limits merging to whole report intervals.
Direction assessment: the revised plan is internally clearer. lite07-finalize.md:19–30 supersedes the previous lite-08 recommendation with an explicit lite-07 route-layer decision and maintainer-controlled cut; the Required list now covers Cluster routing and the full Subscribe ranges line. The HLS live-window policy and the release-specific stats backport are also stated explicitly, with branch reconciliation work recorded rather than implied complete.
Verification limits: reviewed all 32 changed documentation files against current base 21ce561 and compared with the previously reviewed 1e059ab. The intervening main merge's Nix change is outside this PR's current diff. No tests, runtime/hardware validation, or companion-branch integration checks were run; this is not implementation or CI approval.

- Around line 31-35: Update the harness guidance in the benchmark documentation
to retain NTP clock-sync advice for cross-host publisher/subscriber pairs. Note
that subscriber-only mesh invocations may discover publishers from other hosts,

Review comments at @quest/m1/stats/health.md:
- Around line 7-8: Update the health model description to explicitly define
whether rate comes from Transport’s estimate or from cumulative byte-counter

No new actionable findings in the changes since my review of 87ab8af. Direction remains sound:
- snapshot-sequence.md:21–39 generalizes sequence allocation and now explicitly allocates once per catalog update for the hang/hangz pair, with a parity test.
- stats-linger.md:33–45 separates main's planned #4846 totals model from the release backport's per-path handling.
- preflight.md:42–46 now requires an intra-refresh source to pass sync-point checks instead of requiring IDR keyframes.

[P2] Keep transport loss counters separate from gauges — quest/m1/stats/health.md:38–40. The new wording groups loss with RTT/rate gauges and says to read it unchanged. However, schema.md:35–36 specifies bytes/packets lost, and session.rs:64–74 defines these as cumulative totals. Treating those totals as current loss would keep attributing an old loss burst to later healthy intervals. Read RTT and estimated bandwidth directly, but difference bytes_lost/packets_lost with reset handling. Add a shared fixture where the loss total remains nonzero but stops increasing.
Direction: the GPU scope clarifications and explicit HLS dense-input consideration improve the plan; the loss distinction above needs correction. The snapshot-sequence quest and its index entry have now both been removed.
Limits: reviewed the two-commit documentation delta since f330b0b against the unchanged base, plus the schema, reporter contract and session stats. This loss issue is distinct from the previously resolved rate-source comment. No implementation or tests were run.

Make the release test contract match the drop-out option.
This option drops a path's accumulated total and treats its return as a restart. The test requires that no path total goes backwards across the return (Line 55). Either exclude restarted paths from that assertion or remove the drop-out option; otherwise, the plan permits behavior its test rejects.

Derive transport loss from counter deltas.
bytes_lost and packets_lost are cumulative totals. Reading them as reported can use lifetime loss instead of interval loss. Calculate their deltas between snapshots, and reserve “read as reported” for gauges.
Suggested fix
- Rendition rates come from cumulative counters, so a sample is the delta of
- two snapshots over their interval; `transport` gauges (rtt, rate, loss)
- are read as reported, never re-derived, so both languages agree. A reset is detected by a counter decreasing or by the

Define GPU-health behavior when dev_t is absent.
Surface::Vulkan permits a device without a render-node dev_t. The GPU-health API keys snapshots by that value but does not say whether devices without it are excluded or how to identify them. Clarify the health-reporting scope at this boundary.

Clarify the GPU-health reporting scope in the `Surface::Vulkan` documentation
for devices without a render-node `dev_t`: state whether they are excluded from
health snapshots or identify the alternative key used for them. Keep the
documented behavior consistent with the GPU-health API’s snapshot keying.

Problem
moq.pro's 2026-10-05 quest audit found consumer quests there waiting on generic work that no upstream quest owned, or owned at the wrong priority: RTSP import parked in m3 with no consumer, a generic HLS renderer and client health model planned in moq.pro, no quest to finalize lite-07 (so moq.pro's rollout and upstream's mesh condition waited on each other), NVML-only GPU admission, bench percentiles that cannot merge across hosts, and a stats linger whose only plan was in closed #4052. A three-slice audit of this PR then raised the decisions below, which the maintainer settled.
Companion moq.pro PR: https://github.com/moq-dev/moq.pro/pull/2210 (should merge with or before this one; rtsp-import's guide link and stats-linger's moq.pro link resolve only once it lands).
Approach
Quest docs only, each decision recorded in its quest's Plan:
quest/m2/rtsp-import.md) moves from m3 to the top of m2. Its library entry point ingests one session into a caller-suppliedbroadcast::Producer, no reconnect; on a timestamp jump it returns and the caller restarts every session sharing that broadcast under a fresh epoch. The CLI publishes each run under a fresh epoch. Requires Shared import clock; backported torelease(additive).quest/m1/hls-bounded.md: bounded join, capped sliding window even for a durable timeline, stableEXT-X-MEDIA-SEQUENCE,EXT-X-GAPslots, sync-point gating.quest/m1/stats/health.md) and preflight (quest/m1/stats/preflight.md) join the media stats line on the chore(quest): plan media stats as hang tracks and viewer feedback as .echo broadcasts #4510 shapes.quest/m1/lite07-finalize.md) is the mechanical rename and checks done when the maintainer cuts lite-07. It Requires Cluster routing (the route layer lands in lite-07) and the whole Subscribe ranges line.mainmoves AUTH and0x3A UNAUTHORIZEDoff lite-06.quest/m2/gpu-health.md) Requires GPU surface and keys by the render nodedev_t, shared with VA-API import.quest/m1/bench-buckets.md) Requires moq-bench: every README example fails to parse, and cumulative latency percentiles cannot be windowed to steady state #3126 and is backported torelease.quest/m1/snapshot-sequence.md, added by a parallel session from moq.pro's overlay-catalog follow-up): a recreated snapshot or catalog producer resumes past cached groups.quest/m0/stats-linger.md, a standalone m0 quest backported torelease; after the linger a return re-announces under a new epoch.Not added: a gateway
Transportquest.Transport::Rtmp,Srt, andWebRtcalready landed onmainin #3943 but not onrelease, so moq.pro needs the next release cut, not new work.Impact

Follow-ups
Hop Base/Hop Keepcompression.quest/m1/auth/README) still targets lite-06; repoint it at the wip version when it next mergesmain.main, and keepquest/m1/hls-bounded.mdwhen it deletesarchive/hls.md.moq-lite-08-wipframing). Whether the cut opensmoq-lite-08-wipat once is the maintainer's call when cutting.Kind::Autostill matches by device and driver UUID while health and VA-API key bydev_t; the surface carries both. Worth confirming whether Auto should also match bydev_t.(Written by Claude Opus 5.5)
